STUDENT WORK SAMPLES FROM GREECE
Earlystatistics Classroom Experimentation
The EarlyStatistics program was implemented in two departments of two municipal schools of Thessalonica between May 15-29, 2008. An experimental school of the Aristotle University of Thessalonica and the 31st municipal school of Thessalonica took part in the classroom experimentation.
In each of the two schools, participating teachers applied an adapted version of the Scenario Directives on the Implementation of Research: Television developed by the consortium.
Initially the students of the two schools were given the television program of the forthcoming week, and the forms "Daily program of follow-up of programs in the television" in which they would mark daily the TV programs they would watch during the whole week.
The students had at their disposal one week, from Sunday to Saturday, in order to collect the data for their research.
On May 22 we visited the experimental municipal school for the treatment of the data.
The classroom session began with the distribution to all the students of "The recording paper" (a summary data sheet). Each student transferred his/her own primary data from the "Daily program of follow-up of programs in the television" to "The recording paper", where each row of the data sheet corresponds to a program.
Then the students were divided into four groups for the analysis of their data. Each team took a parcel with the data sheets of all students, and the table that they would work with. Each team was given for treatment one of the following tables:
Television channels and programs
Satisfaction with TV attendance (as per type of program)
Duration of TV attendance
Advertising
The first team, that had the table "Television channels and programs", worked with columns 2 and 3 of «The recording paper". First, they wrote in the column "Television channel" all the channels that they had access to, and then they recorded the number of programs that they watched per day on each channel. After completing the table, they calculated the mean daily number of programs per channel, and the total number of programs they watched daily. Based on the table, they constructed a graph (Television channels and programs) per television channel and per day. Finally, they presented their findings to their classmates.
The second team worked with the table "Satisfaction with TV attendance (as per type of program) ". The team worked with columns 6 and 8 of "The recording paper". After finishing the recording, they added horizontally in order to find the sum of programs per level of satisfaction, and vertically to find the sums of each satisfaction level per type of program. Following that, they made a graph (Satisfaction with TV attendance) and announced their results to their schoolmates.
The third team completed the table "Duration of TV attendance". The team worked with the 5th column of «The recording paper ". They added all the quarters that corresponded to each day of the week, and recorded the number that they found in the corresponding square. Next, they added horizontally and divided by 7 in order to find the mean daily duration that corresponds to each student. Then, they added vertically and divided by the total number of students in order to find the mean duration of TV attendance per day of the week. Finally, they drew a graph (Duration of TV attendance) and made a class presentation of the results.
The fourth team worked with the table "Advertising". The team worked with columns 6 and 9 of the "The recording paper" and added horizontally per type and vertically per frequency. This team did not complete the recording, and thus did not produce any graph.
On May 29, we visited the 31st municipal school of Thessalonica for the treatment of the collected data.
The classroom session began with the distribution to all the students of "The recording paper". Each student transferred his own primary data from the "Daily program of follow-up of programs in the television» to "The recording paper", where each row of the data sheet corresponds to a program.
Then, the students were divided into three teams for the processing of their data. Each team took a parcel with the data sheets of all students, as well as the table they would work with. Each team was given one of the following tables:
Television channels and programs
Satisfaction with TV attendance (as per type of program)
Duration of TV attendance
The first team, which got the table "Television channels and programs", worked with the 2nd and 3rd column of The recording paper. Initially, they put down in the column "Television channel" all the channels that they had watched. Next, they recorded the number of programs that they watched per day on each channel. After completing the table, they calculated the mean daily number of programs per channel, and the total number of programs they watched daily. Based on the table, they produced a graph (Television channels and programs) per television channel and per day, and presented the results of the data analysis to the whole class.
The second team dealt with the table "Satisfaction with TV attendance (as per type of program) ". The team worked with columns 6 and 8 of the "The recording paper". After completing the recording, they added horizontally in order to find the sum of programs per level of satisfaction, and vertically to find the sums of each satisfaction level per type of program. The team did not manage to finish the data treatment and to produce a graph.
The third team completed the table "Duration of TV attendance". The team worked with the 5th column of "The recording paper". They added all the quarters that corresponded to each day, and recorded in the corresponding square the number found. The third team was caught up in the coding of the data and did not manage to complete their work.
